DAIRY PRODUCTIVITY OF EWES DEPENDING ON AGE AND LACTATION

Abstract

The milk yield of meat and fat ewes, in particular, the Kazakh fattailed coarse-wool and Kazakh fat-tailed semi-coarse-wool sheep breeds was researched. As a result of the study, it was established that the milk productivity of ewes of the second lactation of the Kazakh fat-tailed coarse-wool breed is 95 kg, and in the Kazakh fat-tailed semi-coarse-wool breed, the milk yield was 102 kg, in the third lactation of the Kazakh fat-tailed semi-coarse-wool breed ewes it was 110 kg, in the Kazakh fat-tailed coarse-wool ewes it was 6 kg less,respectively 104 kg. The average daily milk yield of ewes of the Kazakh fat-tailed semi-coarse-wool breed of the third lactation averaged 0.905 kg, and in ewes of the Kazakh fat-tail coarse-wool breed is 0.059 kg less, respectively, was 0.846 kg. The results of the physical and chemical analysis, in particular, the mass fraction of fat in milk of ewes, depending on the breed of the animal, ranges on average from 8.39 to 9.13%. The average titratable acidity of sheep milk ranges from 22 to 23 ° T.
